ISLAMABAD: The United States and Pakistan are expected to soon reach an agreement to reopen ground routes key for supplying Nato troops in Afghanistan, a Pakistani official said on Monday, in a move that could ease a seven-month crisis in the two countries' ties.

A senior Pakistani security official said that a deal was expected to be announced soon.

US Deputy Secretary of State Thomas Nides departed Islamabad on Monday following discussions with Pakistani officials, the US State Department said.

Senior Pakistani government and defence officials are expected to meet on Tuesday in Islamabad to discuss the latest negotiations with American officials.
